我的问题是,在我的笔记本电脑上安装 Ubuntu 12.04 后,挂起功能不起作用。通过本次培训,我解决了挂起问题。但是从挂起状态恢复后,我的 USB 端口变得不可用。
答案1
有一个比重建内核更简单的解决方案http://ubuntuforums.org/showthread.php?t=1460790 我只需要在我的华硕 N53SV 上解除绑定/绑定
答案2
谢谢,这有帮助。
对我来说,我必须 a) 解除 USB 设备的绑定,以及 b) 手动关闭 wifi。
如果有人发现它有用,这里有一个):
root@tosh:~# cat /etc/pm/sleep.d/20_usb_suspend_fix
#!/bin/sh
LOGTAG=PwrUsbFix
UNDO=/var/run/pm-utils/pm-suspend/storage/rebind_usb.sh
# check am root
[ "$(id -u)" = 0 ] || {
echo "$LOGTAG : must be run as root!"
exit 1
}
case "${1}" in
hibernate|suspend)
: > ${UNDO}
find /sys/bus/pci/drivers -maxdepth 2 -path \*\[eu\]hci\* -name unbind | cut -d\/ -f -6 | \
while read BUS ; do
find ${BUS} -maxdepth 1 -type l -name 00\* | \
while read DEVPATH ; do
DEVICE=`basename $DEVPATH`
echo "$LOGTAG : echo ${DEVICE} > ${BUS}/unbind"
echo -n "${DEVICE}" > ${BUS}/unbind
echo "echo \"${LOGTAG} ${DEVICE} > ${BUS}/bind\"" >> ${UNDO}
echo "echo -n \"${DEVICE}\" > ${BUS}/bind" >> ${UNDO}
done
done
;;
resume|thaw)
. ${UNDO}
;;
esac
exit 0
和 b)
root@tosh# cat /etc/pm/sleep.d/30_wifi_off
#! /bin/sh
MODULES="ath9k ath9k_common ath9k_hw ath"
case "${1}" in
hibernate|suspend)
# Switch wireless off
nmcli nm sleep true
rfkill block 0
rmmod ${MODULES}
;;
resume|thaw)
# Switch wireless on
modprobe ${MODULES}
rfkill unblock 0
nmcli nm sleep false
;;
esac

我遇到了类似的问题。经过一周的搜索,我发现了问题所在。在 Ubuntu 内核中,USB 驱动程序是内置的。因此,在挂起和恢复时,驱动程序无法卸载然后作为模块重新加载。所以我不得不从源代码编译 Linux 内核,并确保 USB 驱动程序(xhci_hcd
和ehci_hcd
)被设为可加载模块。
从那里,我创建了一个名为的20_custom-ehci_hcd
文件/etc/pm/sleep.d/
。

希望这对你有用。我可能在某个地方创建了另一个文件,但我现在找不到它。
我找到了另一个文件。在 中/etc/pm/config.d/
,我创建了一个名为 的文件modules
。
模块
